Medical Definition of Adrenal gland Adrenal gland: A small gland located on top of the kidney. The adrenal glands produce hormones that help control heart rate, blood pressure, the way the body uses food, the levels of minerals such as sodium and potassium in the blood, and other functions particularly involved in stress reactions.he adrenal glands produce hormones that help control heart rate, blood pressure, the way the body uses food, the levels of minerals such as sodium and potassium in the blood, and other functions particularly involved in stress reactions.

adrenal gland Each adrenal gland is a two-part organ composed of an outer cortex and an inner medulla. The cortex arises in the embryo from a region of the mesoderm that also gives rise to the gonads.

- Aldosterone: A hormone produced by the outer portion (cortex) of the adrenal gland. Aldosterone regulates the balance of water and electrolytes in the body, encouraging the kidney to excrete potassium into the urine and retain sodium, thereby retaining water. It is classified as a mineralocorticoid hormone.

Adrenal Insufficiency What is adrenal insufficiency (AI)? The adrenal glands, located on top of the kidneys, make hormones that are essential for body functions. The outer layer (cortex) of the adrenal glands makes three types of steroid hormones. In adrenal insufficiency (AI), the cortex does not make enough steroid hormones.

Alternative names Each adrenal gland is composed of two distinct parts: the outer part called the adrenal cortex and the inner adrenal medulla. The adrenal glands secrete different hormones which act as ‘chemical messengers’. These hormones travel in the bloodstream and act on various body tissues to enable them to function correctly.

Cushing's syndrome The adrenals are two glands, each of which is perched on the upper part of the two kidneys. The outer part of the gland is known as the cortex; the inner part is known as the medulla. Each of these parts of the adrenal gland is responsible for producing different types of hormones.

adrenaline adrenaline. n. 1. (Biochemistry) a hormone that is secreted by the adrenal medulla in response to stress and increases heart rate, pulse rate, and blood pressure, and raises the blood levels of glucose and lipids.It is extracted from animals or synthesized for such medical uses as the treatment of asthma.drenaline-a catecholamine secreted by the adrenal medulla in response to stress (trade name Adrenalin); stimulates autonomic nerve action.

- The adrenal cortex is a part of adrenal gland that is connected to the medulla. This portion of the adrenal gland is responsible for the production of androgens, mineralocorticoids, and glucocorticoids. The glucocorticoids are responsible for increasing the glucose levels in the blood.

aldosterone A hormone secreted by the adrenal glands that is important for maintaining salt and water balance in the body. aldosterone. hormone secreted by the adrenal glands, at a rate regulated by the level of sodium in body fluids. Acts in the kidneys to enhance reabsorption of sodium, reducing its loss in the urine.

What Is the Function of an Adrenal Gland? Function. The adrenal glands are comprised of two parts--the cortex and medulla--that produce hormones (chemicals messengers that regulate body functions).umors of the adrenal glands can secrete excess hormones, causing an increase in blood pressure or heart rate and reducing immune function. Disorders that result in decreased adrenal gland function, such as autoimmune diseases or cancer, can lead to low blood sugar and heart failure.

Adrenal gland Adrenal gland, also called suprarenal gland, either of two small triangular endocrine glands one of which is located above each kidney. In humans each adrenal gland weighs about 5 grams (0.18 ounce) and measures about 30 mm (1.2 inches) wide, 50 mm (2 inches) long, and 10 mm (0.4 inch) thick.

- (Also Called 'Chronic Adrenal Insufficiency'). Addison’s disease is a disorder in which the adrenal glands--which sit on top of the kidneys--do not produce enough of the hormones cortisol and aldosterone. (Hormones are chemicals that control the function of tissues or organs.).

Oxyphil cell (pathology) Adrenal gland. The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: zona glomerulosa, the zona fasciculata and the zona reticularis.

Oxyphil cell (pathology) The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. They are found above the kidneys and consist of a series of layers with different structure and functions. Each gland has an outer cortex which produces steroid hormones and an inner medulla. The adrenal cortex itself is divided into three zones: zona glomerulosa, the zona fasciculata and the zona reticularis. The adrenal cortex produces a class of steroid hormones called corticosteroids, named according to their effects. Mineralocorticoids, produced in the zona glomerulosa, help in the regulation of blood pressure and electrolyte balance.
